Structure
The urogenital triangle is the area bound by a triangle with one vertex at the pubic symphysis and the two other vertices at the iliac tuberosities of the pelvic bone.
Components
As might be expected, the contents of the urogenital triangle differ greatly between the male and the female. Some of the components include:[1]
- Posterior scrotal nerves / posterior labial nerves
- Urethra
- Vagina
- Bulbourethral gland / Bartholin's gland
- Muscles
- Penile crura / clitoral crura
- Bulb of penis / vestibular bulbs
- Urogenital diaphragm
- Muscular perineal body
- Superficial and deep perineal pouch
- Blood vessels and lymphatics
